PNG to WebP Converter

Turn PNG files into WebP right in your browser — drag in one image or thirty. Files are converted in your browser and never uploaded.

Quick answer

WebP keeps transparency like PNG but is usually much smaller, which makes it the better format for website images. Every current browser supports it.

About the PNG to WebP converter

PNG is best for logos, screenshots, text and anything with transparency — lossless, but photos come out large. WebP is best for websites — usually 25–35% smaller than JPG at similar quality, with transparency support.

PNG to WebP is one of the easiest wins for website speed: transparent PNG graphics often shrink by more than half as WebP while keeping their transparency.

All modern browsers support WebP. If you also need to email the image or open it in older software, keep the PNG as well.

How to use it

  1. Drop your PNG files on the box above, click “Choose files”, or paste an image.
  2. Check the output format is WebP and set the quality (85–92% is a good balance).
  3. Click “Convert to WebP”.
  4. Download each image, or use “Download all”.

Frequently asked questions

Are my images uploaded to a server?

No. The conversion uses your browser’s built-in image engine, so the files stay on your device. That also makes it fast — there is no upload or download wait.

Does WebP keep transparency?

Yes. WebP supports an alpha channel, so transparent backgrounds are preserved.

Which quality should I pick for graphics?

Start at 90%. Flat graphics and logos stay crisp, and files are still much smaller than PNG.

Can I convert several files at once?

Yes. Add up to 30 images and convert them in one go, then download them individually or all together.
